How to cut down a tree using a 'Tree House'

An impressive video of a rotating tree house, with a chainsaw attached, cutting down a tree.

The footage, filmed in Montana, USA last year, shows the tree house moving slowly in a circle while the chainsaw roars in the background. It eventually takes down the tree that was stopping the wood house from rotating a full 360 degrees.

The filmer later wrote online: "We built a tree house that rotates, but there was a tree in the way, so we cut it down by strapping a chainsaw to the tree house and rotating it through the tree."
